After last update, cursor has become sluggish with low fps.
However, dragging windows, scrolling in a web browser or working in OpenGL 3D window all appear to work at the proper refresh rate. These actions also increase refresh rate of cursor, if cursor is over area that is being updated.
Also now getting momentary screen blackouts that last a few seconds, then screen comes back.
Here's a snip from inxi -Fxxxz:
